说明：  滚动轴承故障诊断是机械故障检测中一个重要方面。使用小波包分析和包络分析相结合的方法提取轴承微弱振动信号, 克服了传统包络分析方法易丢失信号有效成分的缺点。包络信号的细化谱较好体现了轴承故障信息。(Bearing Fault Diagnosis of mechanical fault detection in an important aspect. The use of wavelet packet analysis and envelope analysis method of combining extracts bearing vibration signal weak to overcome the traditional envelope analysis method easy to lose the signal disadvantage of the active ingredient. Refinement of the envelope signal spectrum better reflects the bearing fault information.)

end point detection or silence removal i.e to remove voiced or unvoiced speech

元胞自动机：森林火灾模型程序代码及其讲解，好好看看哦，加油(Cellular automata: the model code of forest fires and their explanations, a good look, oh, come on)

说明：  压缩感知代码,在matlab编程环境中实现。代码结构清晰易懂。(code of compression perception)

WAVELET CODING FOR IMAGE

This is a matlab program that computer the gradient image using 1st derivative of Gaussian

可以实现十进制转换成任意字长的二进制。并又可以按照这个二进制转换成十进制。这个程序对于分析不同字长对于IIR数字滤波器和FIR滤波器的影响是非常有用的。(Decimal to convert any word length of the binary. And also in accordance with this binary to decimal conversion. This program is very useful for the analysis of the impact of different word length for the IIR digital filter and FIR filter.)

粒子群算法源代码,属于进化算法的一种，和遗传算法相似，它也是从随机解出发，通过迭代寻找最优解。(Particle swarm algorithm source code, is a kind of evolutionary algorithm, and genetic algorithm are similar, it is also starting from the random solutions, through the iterative search for the optimal solution.)

多小波中应用最多的就是DGHM多小波，该多小波有很好的去噪效果。(Multiwavelet Medium is the most widely used DGHM multiwavelet, the multiwavelet denoising has very good effect.)
